A special machine is used at a construction site to dig holes. A hole is dug to a depth of 4.75 feet when the machine hits rock. The progress slows to 3/5 feet per hour of digging. The depth of the hole must be at least 12 1/2 feet by the end of the day to stay on schedule. What is the minimum amount of time the machine must continue at its present rate to complete the hole on schedule? Select from the drop-down menus to correctly complete the statement.
Answer: 12 h ; 45 m
Step-by-step explanation:
*Important: From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.
What we know:
Progress has been made to 4.75Rate of digging is 3/5 mphDepth must be at least 12 1/2We need to find the minimum amount of time the machine worksHow to solve:
By setting up an algebraic equation, we can solve this.
Process:
Set up equation 4.75 + 3/5x = 12 1/2Convert 19/4 + 3/5x = 12 1/295/20 + 12/20x = 250/20
Subtract -95/20 -95/2012/20x= 155/20
Isolate x via division /(12/20) /(12/20)+Simplifyx= 12 11/20
Convert 12 h 33 mSolution: 12 ; 45
The minimum amount of time taken by the machine will be 12 hours and 55 minutes.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
An exceptional machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the machine hits the rock. The advancement eases back to 3/5 feet each hour of digging. The profundity of the opening should be no less than 12 ¹/₂ feet before the day's over to remain on time.
Convert the mixed fraction number into a decimal number.
12 ¹/₂ feet = 12.5 feet
Let 'x' be the time. Then the equation is given as,
(3/5)x = 12.5 - 4.75
Simplify the equation, then we have
(3/5)x = 12.5 - 4.75
(3/5)x = 7.75
x = 12.9167
x = 12 + 0.9167 x 60
x = 12 hours and 55 minutes
The base measure of time taken by the machine will be 12 hours and 55 minutes.

Answer:
y = 2x
Step-by-step explanation:
the equation of proportional relationships are in the form y = mx, where m is the slope.
this means you need to solve the slope.
to find the slope, find 2 random points and do change in y divided by change in x.
for example, (3, 6) and (0, 0)
this would be (6 - 0)/(3 - 0) = 2
this means m = 2
so the equation is y = 2x

A washing machine is filling up with water at a constant rate. The rate is Three-fourths of a gallon in 1 over 5 of a minute. Don calculated the unit rate to be 3 over 20 of a gallon per minute. What did he do wrong?
Answer:
First, you have to see how many gallons fill in a minute, obviously, so take 3/4 and divide it by 1/5, which gives 15/4. so you can see, don multiplied the two numbers instead of dividing, which is what he did wrong.Step-by-step explanation:
Answer from NukeExplosions1
Answer:
What he did wrong is that he multiplied the denominator wrong. it is supposed to be a 15. Don should re-calculate it to 3 over 15 of a gallon per minute.

Please answer this 3 questions and show your work
Answer:
Step 1: Circle 16, 5.75, and 296.00
underline "What was the regular price ticket to the game?"
box "bought", "rate", and "paid"
Step 2: 296.00 = 16(t-5.75)
Step 3: 12.75
Step-by-step explanation:
Step 2: the total price paid is 296 so that is what goes on the equal side of the equation.
t is the normal ticket price and 5.75 is the discount so we want to subtract 5.75 from the normal ticket price to show what we paid.
Then, we want to multiply by 16 because we bought 16 tickets.
Step 3: distribute the 16 to the (t-5.75) term. That gives you 296= 16t-92
Then subtract 92 from 296 to give you 204. then divide by 16 to give you 12.75 as your ticket price.

Answer:
29 inches
Step-by-step explanation:
For the following I just used trial and error and experimented with the possibilities:
29 inches - This is the only one that does not work.
30 inches - We can use 5 of the 6 inch trains, so this is possible.
31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.
32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.
33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

Answer:
avn= -8 + (n-1)(-7)
Step-by-step explanation:
arithmetic sequence formula= avn= av1 + (n-1)d
av1= first number in the sequence
d= common difference
n= the number of the term to find
The common difference is -7 so d=-7 and you plug it into the equation. The first number in the sequence is -8 so av1.
There is no specific n to find so it remains n.
I hope this helps! Let me know if this helps.

The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. Each flower head produces 1,000 seeds. You decide to harvest the seeds at the end of the season so that you can sell them the following spring. If you save 8 flowers for harvesting, how many seeds is that? Write your answer in scientific notation.
Answer:
8*10^3
Step-by-step explanation:
The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. - All of this information is useless, all the question is asking is how many seeds do 8 flowers produce.
Each flower head produces 1,000 seeds. If you save 8 flowers for harvesting, how many seeds is that? - 1000*8 = 8000. 8000 is scientific notation is 8*10^3, as 10^3=1000, and 1000*8=8000 seeds.
